We are going to a candle for burn tests on fiber samples. We will have 12 to 15 unknowns with one to two mixtures containing two of the solids with asterisks.
Solid= sand(white), powdered limestone, vitamin C, table salt, sugar(crystal), flour, gypsum, corn starch, baking soda, powdered gelatin, powdered Alka-Seltzer
October 1,2008
In Science Crime Busters (SCB) the collected evidence and other data given could be used in a mock crime scene analysis to solve a crime problem. A scenario will be developed such as the following: a bank robber enters a bank and hands the counter person a note, which says "Give me all your money" The robber escapes with the money, but a white powder remains. later, suspects are brought in. Chromatographic analysis of the ink from their pens is proformed an order to identify the robber. Each suspect's powder is then compared with the powder found at the crime scene, and so on.
October 3, 2008
The Competition: There will be 4 parts and then the analysis of the Crime.The event will consist of evidence from parts 3a, 3b, and 3c at all the competitions and up to 2 parts of the crime scene physicle Nationals. All competitions will require the analysis. Questions can only be asked on the evidence areas found at the Crime Scene, so for instance if DNA was not one of the pieces of evidence found at the crime scene, no questions about DNA can can be asked.

a)qualitative analysis:the unknown common matierials will be taken from the following lists.
i.solids:anhydrous sodium, acetate, *sand(white), *calcium carbonate(powdered limestone), vitamin C(ascorbic acid), *table salt(NaCl), *sugar(crystal), *flour, *gypsum(calcium sulfate 2h2o), *corn starch, *baking soda, *powdered gelitan, *powdered Alka-Seltzer, yeast.
ii.Non-powdered metals: aluminum, iron, zinc, magnizeum, copper, and tin.
iii.liquids: lemon juice, rubbing alcohol(isoporpyl), household ammonia (3%), water, vinagar, hydrogen paroxide(3%).
October 24,2008
at the regional competition, we will have 12-15 unknowns with one to two mixtures containing two of the solids with asterisks. at the state level, we will have 15-18 unknowns and will have at least 2 mixtures containing 2-3 of the solids with astrisks. at the national level, we will have 18-20 unknowns with at least two mixtures containing at least 2-3 solids with astrisks. the unknowns will be identified by preforming tests such as solubility, acidity, magnetic property, color, density (by hefting the sample in its container), and odor. every team gets the same set of unknowns and the scenario will identify which containers hold the mixtures.

Today we did the finger printing nd hair analysis work sheets.
The activiy sheets are in our science plympiad binder.
In the competition there is a god chance that we will have to study finger prints of all of the finger prints and hair of several suspects, counting animals.

Today and yesterday, we are sorting all of the chemicals and other things in our box of stuff to bring. we need to see what we can bring and what we will get disqualified for. we will sort it and put the stuff that we can't bring into another box. we will label the "bad" box and put it in the storeroom.
December 1, 2008
Today in science olympiad we are seeing what we will have to do, and how to do it. like the hair and finger samples. we will also do things with our box and probably re-mark all the bottles.
December 2, 2008
we are doing the same thing yesterday, and rying to finesh it.
December 3, 2008
Today my partner, nate, is gone, so i will be looking at the S.O. website and looking to get an insight on how nate and i are going to have to do the hair samples and finger print examination.
if it is complicated and we have to have a certain type of equipment, we will get it, and do more research. if its the exact opposite, we will get an even better insight on the event.
i just found out that there are different hairs for different races!

today i will show nate what i did yesterday, and continue the study.
December 5, 2008
today we are going to study part two (above=part 1) on sinthetic and natural fibers in a crime scene. if we finesh fibers, we will go on to pt. 3, Crime and Evidence.
January 5, 2009!!!!!!
today we are practicing finger prints and searching for websites that might help us in competition.

today, after school, me, sam, and, zach found out how to find the ph levels of solids. it took a lot of time to find them all and write them down. scince sams handwriting is really bad. i will typ our findings about each chemical tomorrow cause i ran out of time today.
